HOOP- COILING MACHINE.

SPECIFICATION forming part ofjLetters Patent No. 223,968, dated January27, 1880.

- Application filed July 10, 1879.

To all whom it may concern:

Be it known that I, ALEXANDER F. WARD, of Ohatham, in the county of Kentand Dominion of Canada, have invented an Improvement in Hoop-CoilingMachines, of which the following is a specification.

The nature of my invention relates to new and useful improvements inthat class of machines employed in coiling hoops for shipment; and theinvention consists in the construction of the several parts and theirarrangement and combinations, as more fully hereinafter set forth.

Referring to the drawings, Figure 1 is a perspective view with the gatethrown open. Fig. 2 is a horizontal section through the center. Fig. 3is a perspective of the inner face of the head and attachments to theend of the hollow shaft. Fig. 4: is an elevation enlarged and with thegate removed. Fig. 5 is an enlarged detail, showing the spring finger ordog which confines the end of the hoop first fed into the machine. Fig.6 is aside elevation.

Like letters indicate like parts in each'figure.

In the accompanying drawings, which form V a part of this specification,A represents the frame of the machine, which carries the working partsthereof, and upon it is journaled, in suitable boxes at, the hollowshaft 1), upon the end of which is secured the hollow head 0,

the rim of which is finished upon the outside like a smooth pulley, towhich motion is communicated by the friction-pulley d, which is securedto a counter-shaft, e, which runs in the shorter arm f of the lever g,by means of which .thefrietion-pulley is thrown into or out ofengagement with the outer face of the head, as

desired. This lever is fulcrume'd on the rod h, and upon thecounter-shaft is another pulmotion in boxes 0 on the frame, near therear end, while their front ends pass through the front of the frame, asshown in Figs. 1, 2, and

6. To the front end of one of these rods is hinged, at p, the gate 0,which, when closed, engages with the other rod, and is secured by thespring-1atch s. The rear ends of these rods a pass through the yoke t,in which they are made adjustable by means of the setscrews a. To thecenter of the yoke is adjustably secured, by means of the screw orthreaded end and nut c, the shaft w, which passes through the hollowshaft 1) and head c, and upon its end is rigidly secured the spider aswith three arms, as shown in Fig. 3, each arm terminating in right-angleprojecting studs 2. Motion is communicated to this shaft to from thehead 0 by the engagement of the. studs l with the arms of the spider no,as shown in Fig. 3.

At one end of the yoke tthere is pivoted, by means of the set-screw a, aconnecting-rod,

a, the opposite end of which is pivoted, by a,

suitable wrist-pin, to the crank b, which is rigidly secured to therock-shaft c. To the opposite end of the yoke t there is pivoted, bymeans of the set'screw a, a similar connecting-rod, d, the front end ofwhich, by a suitable wrist'pin, is pivoted to the bell-crank e, which isrigidly secured'to the opposite end of the rock-shaft '0. Theseconnecting-rods and cranks are so pivoted together and arranged withrelation to each other that when the yoke is retracted, as shown in Fig.6, it cannot he accidentally projected, as the pivotal connection at oneend of the connectingrodsis below the point of pivot on the yoke, sothat one looks the other.

To the bell-crank e is pivoted the connect ing-rod. f by means of thewrist-pin g. The lower end of this rod f is pivotally secured to theshorter arm h of the treadle t". This .treadle is secured to therock-shaft 7c, and to 0 its longer arm l is secured the counterbalanceweight m. Pressure upon the treadle will project the yoke and gate withtheir attachments, and, the pressure being relieved, the weight on willretract the same.

The points of connection between the weight and .treadle and therock-shaft and between the cranks of the rock-shaft and the yoke t areso adjusted that when the weight strikes the floor in moving the doorback to place I00 against the coiling-barrel the cranks will have moveda short distance below their centers,-

outer ends are just within the front face of the disk. To this frontface is secured the annular ring or short barrel 0, with a short segmentcut out, as at r. A clutch-finger, p, is secured to the front face ofthe disk by means of the set-screw s, which passes through the slot tthrough said finger. A lever, a, is pivoted through the disk, so thatits outer end projects through the same and enters the slot '0 in theclutch finger or dog 19, and its opposite end engages with thesquaredfside of the spider-head to, so that when the latter is retractedwith the yoke the lever will compel the dog to perform the function forwhich it is designed, and when the yoke and its attachments areprojected the lever will release the dog. A leaf-spring, 00, one end ofwhich is rigidly secured at y, engages with the notch z on the side ofthe dog, to hold the same upon its movable fulcrum, made by the slot tand set screw 8, and allows the dog to act upon thinner or thicker hoopsas they may be presented. Thecrank B is pivoted through apro jection, O,of the frame, and has an arm, D, rigidly secured to it, at the lower endof which is fastened the weight E. To this crank is removabl y securedthe band F, which passes under the ring or barrel 0, and its oppositeend is removably secured toa swinging support, G, pivoted to the frontof the frame. A vertical rod, H, has a reciprocating motion in bearingsI in the front of the gate r. A coilspring, K, through which said rodpasses, is so arranged as to keep the rod elevated, except whendepressed by pressure upon thefootpiece L. The upper end of this rod isbent backward to form a detent, M, for the purposes hereinafterdescribed.

In practice, with the machine constructed as above, the yoke, with itsattachments, is retracted, as shown in Fig. 2, with the gate closed. Theend of a hoop is inserted through the cut-away portion of the ring orcoiling-barrel between the inner edge thereof and the point of the dog,which gives upon its movable fulcrum to receive the end of the hooppresented. Themachine is then started, when the hollow head commencesrotating, its studs engaging with the arms of the spider, compelling theshaft 20 to also rotate, .whenthe projections or studsz of the arms ofthe spider are presented through the holes in the disk, which is securedupon the studs 1, and is thereby caused to rotate, coiling the hoop onthe outside of the annular ring or coiling-barrel, against which it isheld by the band F, the proper tension of which is secured by the weightE upon the arm, which secures said weight to the crank B, to which oneend of the ban d is secured. The lap of the next hoop presented isinserted under the end of the coiled hoop, and so the next, until theroll or coil of hoops is as large as required, when pressure upon thefoot-rest L compels the bent end or hook M of the rod H to rest upon thefree end of the last hoop coiled and hold it until it is nailed. Thenpressure upon the treadle 4." will project the yoke t, with itsattachments and gate 1*, to the front, when the studs 2, projectingthrough the coiling-disk m, will force the coil of hoops from the ringor coiling-barrel, and such coil will then drop to the groundthrough thespace between the gate and disk caused by projecting the yoke and itsattachments, which at the same time disengages the spider-head w fromthe lever u, thereby releasing the dog. The yoke and its attachments arethen retracted by relieving the pressure on the treadle, and the machineis in readiness to coil another roll of hoops. Should a hoop break inthe process of coiling, the gate should be thrown open, as showninFig.1, after releasing the spring-latch s, when the broken hoop is easilyremoved.

The adjustability of the yoke upon the side rods and center shaft willallow the machine to be employed in coiling hoops of different widths.

I am aware of the patents granted to J.

Tomlinson and J. H. Ward, and numbered,

respectively, 159,289 and 209,735, and hereby disclaim the same.
